Investigating officer Det Supt Chris Ward said: “This is very much still an open investigation and we are continuing to appeal for witnesses and any information.
“We believe there could be other offenders and so we are currently concentrating on determining exactly what happened on Sunday night.
“A scene watch remains in place and I want to thank local residents once again for their help and patience whilst investigations continue.
